Add a method allowing to know what is the name of the "method" passed in the request
Methods can be specified in a form in the JSP, for submit buttons and you can use them in links too.
Add a method in ActionSupport called String getActionmethodName()
if you submit .... method:save it would return "save" etc.
I use a an equivalent method to do some security logic in my actions if multiple methods can hit the same action
